Fig. 13-60 Gaging Rear Thrust Race
24. Remove rear cylinder half and carefully
remove one piston at a time from swash plate
and front cylinder half. Do not lose the relation-
ship of the front ball and shoe disc and rear
ball. Transfer each piston, ball, and shoe disc
to its proper place in Parts Tray.
25. Remove rear outer zero thrust race from
shaft and install thrust race previously selected.
NOTE: The zero thrust race may be put
aside for re-use in additional gaging or re-
building operations.
41. Compressor Internal Mechanism,
Assembly
1. Install a piston ring on each end of #1 piston,
with scraper groove toward center of piston.
2. Lubricate ball pockets of piston with re-
frigeratdon oil and place the corresponding balls
from the Parts Tray in each pocket.
3. Lubricate cavities of #1 piston shoe discs
with refrigeration oil and place zero shoe disc
over ball in front end of piston and numbered
shoe disc over ball in rear end of piston.
4. Rotate shaft and swash plate until high point
of swash plate is over #1 piston cylinder bore.
NOTE: Make certain that front thrust race
and bearing assembly adhere to swash plate
hub.
5. Position piston over #1 cylinder bore (notch-
ed end of piston on bottom and piston straddling
swash plate) and lower shaft to allow piston to
drop into its bore.
6. Position piston ring gap toward shaft, com-
press ring and lower ring into front cylinder
half.
7. Repeat steps 1 through 6 for pistons #2 and
#3.
8. Install new discharge crossover tube in front
cylinder half with bridged surface facing out-
board, Fig. 13-61. Make certain that end of
tube is properly centered in hole in front cylin-
der half.
NOTE: The service discharge crossover
tube is similar to the production type tube
except that an O-ring and bushing is used at
each end, Fig. 13-62. Do not install O-ring or
bushing at this time.
9. Rotate shaft to position pistons in a stair-
step arrangement. Position rings on each piston
so that ring gaps are toward shaft, then push
rings as far outboard as possible.
10. Place rear cylinder half over shaft and
start pistons and rings into cylinder bores.
11. When all three pistons and rings are in
their respective bores, align end of discharge
crossover tube with hole in rear cylinder half.
Make certain that bridged surface of tube faces
outboard for swash plate clearance.
12. When satisfied that all parts are in proper
alignment, tap rear cylinder half with a mallet
to seat it over the locating dowel pins.
13. Remove internal mechanism from fixture
and place on bench.
